1 Safety precautions General safety guidelines WARNING! Internal circuits use hazardous voltage capable of causing death or serious personal injury. No operator serviceable parts inside. Refer servicing to qualified service personnel. The disconnecting devices for servicing are two Branch Circuit Breakers located in the building's Power Distribution Unit (PDU). Electric shock hazard Due to risk of electrical shock, do not attempt the following actions: ● Dismantle the electrical control cabinet.

Safety precautions Fire hazard CAUTION: The drying and curing subsystems of the printer operate at high temperatures. To avoid the risk of fire, take the following precautions when operating the printer: ● Do not manipulate the heating modules. ● Load substrates that withstand temperatures of 125°C. Heavy substrate hazard Special care must be taken to avoid personal injury when handling heavy substrates. ● Handling substrate rolls always requires at least two people. Care must be taken to avoid

Safety precautions Label Explanation When the printer is printing, the printhead carriage travels back and forth across the substrate. Beware of this moving part. Emergency stop buttons There are four emergency stop buttons distributed around the printer. If an emergency occurs, simply push one of the emergency stop buttons to stop all printing processes. A system error message is displayed on the front panel, and the fans turn at maximum speed. Ensure that all emergency stop buttons are release

2 Printer status Check printer status You can check the current status of the printer in the following ways: The HP Internal Print Server displays the status of the printer, the loaded substrate and the ink ● system. The latest alerts are summarized at the bottom of the main window (see Printer alerts on page 5). The front panel displays the ink levels by default; otherwise, you can see the ink levels by selecting ● the the Ink System icon . In addition, the most important current alert, if any,

Printer calibration 3 Printer calibration Align the printheads Precise alignment between printheads is essential for color accuracy, smooth color transitions and sharp edges in graphical elements. To align the printheads, go to the HP Internal Print Server and select Printer > Printhead alignment. You can select automatic or manual alignment; the HP Internal Print Server will recommend one or the other, but you can always choose. ● Automatic alignment is a fully automated procedure that ensures

Troubleshoot printhead alignment Automatic printhead alignment may fail occasionally. In some cases, you may see the front panel error message "Automatic Printhead Alignment is cancelled because of scanning errors". In other cases, there is no error message but the print quality is not satisfactory. Here are some possible explanations. There is some problem with substrate advance (see Substrate-advance compensation ● on page 7). After fixing any substrate-advance issue, retry automatic printhead

Printer calibration You can view and change the substrate-advance compensation of the currently loaded substrate at any time from the HP Internal Print Server by selecting the print job and then the Printing Adj. button, or by selecting Printer > Printing adjustments. If you prefer the print quality after changing the figure in the Advance field, press the Apply button, and thereafter your preferred substrate-advance compensation will always be used for that particular substrate type. The substr

The calibration process is fully automatic and can be performed unattended after you have loaded substrate of the type you wish to calibrate. The process takes about 18 minutes and consists of the following steps. 1. The Closed-Loop Color Calibration and Ink Restriction Test Chart is printed, which contains scales of patches of each ink used in your printer. 2. The test chart is scanned and color-measured using the HP Embedded Spectrophotometer. If the scan cannot be completed successfully, a me

Printer calibration Color calibration is based on the color measurement of printed color patches, using the HP Embedded Spectrophotometer. Some characterisitics of substrates, such as surface roughness or transparency, may make reflective color measurement of some substrate types very inaccurate. Color calibration of these substrates will fail or produce unacceptable printing results. The suitability of particular substrate types for color calibration can be found in the table of supported subst

4 Hardware maintenance Maintain the ink cartridges During the normal lifetime of a cartridge, no specific maintenance is required. However, in order to maintain the best print quality, replace a cartridge when it reaches its expiration date. An alert notifies you when any cartridge reaches its expiration date. You can also check a cartridge's expiration date at any time: see Check printer status on page 5. Maintain the printheads During the normal lifetime of a printhead, no regular maintenance

Hardware maintenance 4. Standing at the front of the printer, clean the front rail using a lint-free cloth dampened with isopropyl alcohol. You can access the rail from above. NOTE: If you are in California, instead of isopropyl alcohol please use a VOC-certified cleaner such as a properly diluted 'Simple Green ® All-Purpose Cleaner'. 5. Standing at the rear of the printer, clean the rear rail in the same way. You can access the rail from below, through the gap between the platen and the pinches
